Limit value: The maximum or minimum limit val ue that should not be exceeded at inspection and adjust-
ment.
UnitsINFOID:0000000006280837
 The UNITS given in this manual are primarily expressed as the SI UNIT (International System of Unit), and
alternatively expressed in the metr ic system and in the yard/pound system.
Also with regard to tightening torque of bolts and nuts, there are descriptions both about range and about the
standard tightening torque.

ContentsINFOID:0000000006280838
 A QUICK REFERENCE INDEX , a black tab (e.g. ) is provided on the first page. You can quickly find the
first page of each section by matching it to the section's black tab.
 THE CONTENTS are listed on the first page of each section.
 THE TITLE is indicated on the upper portion of each page and shows the part or system.
 THE PAGE NUMBER of each section consists of two or three letters which designate the particular section
and a number (e.g. “BR-5”).
 THE SMALL ILLUSTRATIONS show the important steps such as ins pection, use of special tools, knacks of
work and hidden or tricky steps which are not s hown in the previous large illustrations.
Assembly, inspection and adjustment procedures for the complicated units such as the automatic transaxle
or transmission, etc. are presented in a step-by-step format where necessary.

Relation between Illustrations and Descriptions
INFOID:0000000006280839
The following sample explains the relationship between t he part description in an illustration, the part name in
the text and the service procedures.
ComponentsINFOID:0000000006280840
 THE LARGE ILLUSTRATIONS are exploded views (see the following) and contain tightening torques, lubri-
cation points, section number of the PARTS CATALOG (e.g. SEC. 440) and other information necessary to
perform repairs.
The illustrations should be used in reference to service matters only. When ordering parts, refer to the appro-
priate PARTS CATALOG .
Components shown in an illustration may be identified by a circled number. When this style of illustration is
used, the text description of the components will follow the illustration.

HOW TO FOLLOW TROUBLE DIAGNOSES
HOW TO FOLLOW TROUBLE DIAGNOSES
DescriptionINFOID:0000000006280841
NOTICE:
Trouble diagnoses indicate work procedures required to diagnose problems effectively. Observe the following
instructions before diagnosing.
 Before performing trouble diagnoses, read the “Work Flow” in each section.
 After repairs, re-check that the problem has been completely eliminated.
 Refer to Component Parts and Harness Connector Location for the Systems described in each section for
identification/location of components and harness connectors.
 When checking circuit continuity, ignition switch should be OFF.
 Refer to the Circuit Diagram for quick pinpoint check.
If you need to check circuit continuity between harness connectors in more detail, such as when a sub-har-
ness is used, refer to Wiring Diagram in each individual section and Harness Layout in PG section for identi-
fication of harness connectors.
 Before checking voltage at connectors, check battery voltage.
 After accomplishing the Diagnosis Procedures and Elec trical Components Inspection, check that all harness
connectors are reconnected as they were.
